To all whom it may concern:

Be it known that I, Giusnrrn RUBINO, a subject of the King of Italy, andresident of liarriesa, Urocetta, Turin, Italy, have invente'd certainnew and useful Improvements in Rims for Pneumatic-Tired vi heels ofwhich the following is a full, clear and exact specification.

This invention. relates to a new form of s notional or separate rim forpneumatic tired \\'lu -els designed to facilitate the mouldingv of anair-tube or cover therefor or both.

l")ismountable rims for pneun'iatic tired wheels used hitherto aresomewhat COH'IPll' catcd and have a seating for the pneumatic tire inthe form of aJCehaped annular rim in. :1. single piece so that theapplication of a new air tube or cover canhot be rapid owing to the(Lliliiculty of introducing into the rim the thict part of the cover, adiilioulty which o ten causes deformations arid den;- age to the airtube. 7

lly the present invention a metallic rim which. retains the ii-shape,not made in a single piece but in two parts which one can easilyseparate so as to avoid completely the aforesaid difficulty Itconstruction in accordance with the invention is shown in theaccompanying drawings in which Figure 1 is a. section through in. in itsclosed position and Fig. 2 is a view in the open position *im couf oftwo parts suitably l J 5.

screw threaded brackets or lugs F which receive screw bolts C adapted tohold the part D of the rim in its operative relationshig to part A.

y removing the bolts C the part D of is the rim may be entirely removedand the cover and the air-tube withdrawn from or mounted on the rim withgreat ease.

Having now particularly described and ascertained the nature of myinvention and 5a in what manner the same is to be performed I declarethat what 1 claim is:

\ it sectional rim comprising two members one having a tireeiiigaging-ila nge on one side and also having an inner ring; the saidinnor ring being spaced from said member at the side opposite said.flange and being provided at said side with an internal flange, and.said member being turther provided with lugs secured to said inner ringand arranged in the angle between said inner ring till end its inturnedflange, said lugs and in turned flange having" screw-receiving openlugs;the other member being telescopically fitted between the first namedmember and the spaced portion of its inner ring and. being also providedwith a tire engaging flange and an inwardly extending and screwsextending through openings in said inwardly extending flange and havingit! threaded engagement in the openings of the said h in witnesswhereof, I have hereunto signed me in the presence of two subscribinglillllllli').
